Features


  • Principle of Operation: Porro Prisms utilize total internal reflection (TIR) to reflect light beams, ensuring that the beam emerges parallel to itself.

  • Coating Options: For applications where the acceptance angle for TIR is exceeded or surfaces cannot be kept clean, metal or dielectric coatings can be applied to the reflecting surfaces.

  • Material Options: Available in BK7, UVFS, and FS materials, providing flexibility for various optical applications.

  • Surface Figure: All polished surfaces offer a surface figure of λ/20 at 633 nm, ensuring high precision.

  • Surface Quality: High-quality finish with a surface quality of 10-5 for all polished surfaces.

  • Dimensional Tolerance: Precision manufacturing with a dimensional tolerance of +0.000", –0.010".

  • Angular Deviation: Maintains an exact angular deviation of 180º for consistent performance.

  • Bevels: Features 0.010" – 0.030" bevels at 45º on the input edge, with a minimum safety bevel on roof edges for added protection.

  • Clear Aperture: Provides a clear aperture exceeding the central 85% of the diameter, ensuring maximum light transmission.

Applications


  • Binoculars: Porro prisms are commonly used in binoculars to provide a wider field of view and better depth perception.

  • Cameras: Used in some camera systems to correct image orientation and improve optical performance.

  • Telescopes: Employed in telescope designs to enhance image clarity and brightness.

  • Periscopes: Utilized in periscopes for their ability to reflect light and provide a correct image orientation.

  • Optical Instruments: Integral in various optical instruments where image inversion and reflection are needed.

  • Scientific Applications: Used in scientific equipment for precise light manipulation and measurement.

  • Laser Systems: Incorporated in laser systems for beam alignment and control.

  • Medical Devices: Used in medical imaging devices to enhance visualization and accuracy.
